Wireless technologies have reached an impressive popularity in the last years. However, the radio spectrum is very limited, and therefore as wireless communications have become more and more widespread, problems related to spectrum scarcity have arisen. Radio spectrum, as the physical support for wireless communication, both for fixed applications and especially for mobile broadband, is becoming an extremely strategic, valued, and demanded resource. Therefore, technologies and techniques enabling a more flexible access for service providers and clients and a more efficient and effective usage are needed.
